Removed lambda docstrings (they are better in the separate_api branch).
Long haul: Fixed ability to run PySide and PyQt4 side-by-side without having to re-make ui files. The trick was to set __path__ in ui/__init__.py to make the interpreter look in pyside_ui subdir for submodules if PySide is selected. There is still an issue where the UI does not load if running code.interact with PySide (until you press Ctrl+D), but you can still run through ipython, so not a big deal.
